Toma, whose undercover career in Newark, NJ became a TV show in the early '70s, went on to a career in anti-drug public speaking.
This hardcover's jacket is worn at the spine and edges, and the pages are very slightly toned (plus a few towards the back look like they took a hit with some spilled coffee, but only on the edges). For a 50 years old, it's in pretty good shape and features some interesting production choices.
